For me ill use bitcoin because im a newbie i think ahahaha and im still learning what its full potentials.
The answer to this question should be pretty obvious and straightforward. Gold is for long-term investment while bitcoin is for short-term speculation, at least for me. Other people, indeed, may have their own reasons why they are voting for gold and continue using bitcoin (if they really are, in the first place)...
I would actually say the opposite, I see btc as a long term inversion.
However, I imagine most vote for gold simply because it's still a safer investment vehicle.
